11. SWITCHING THE COMPRESSOR ON
Fig.4
Switch on the compressor at the pressure switch (2) by turning the
knob (3) to position “I.”, The compressor sends pressurized air to the
air tank. As the compressed air is used, the pressure in the air nozzle
drops to a preset level, the compressor switches on and the air nozzle
files with compressed air. After reaching the cutoff pressure the
compressor turns off automatically and the cycle is repeated. Check
the value of switching-on and switching-off pressure on pressure
gauge. The values may be within a tolerance of
10%. Air pressure in
air chamber must not exceed maximal permitted operation pressure.
Never tamper with the pressure switch (2). Adjustments are not allowed. The pressure
switch (2) has been set by the manufacturer and further setting of switching on and off
pressure may be carried out only by a qualified expert trained by the manufacturer.
